asteroidOne of billions of rocky objects, less than 1000 km in diameter, which orbit the Sun. Also known as minor planets. Thought to be planetesimals leftover from the formation of the planets. The first asteroid (Ceres) was discovered by Giuseppe Piazzi in 1801. More than 10 000 asteroids have so far been discovered and given permanent identification num [..]

asteroidSmall, rock-like objects that orbit the sun. Most are found in an asteroid belt between the orbits of Jupiter and Mars.
|
9 |
asteroidA solid body orbiting the Sun that consists of metal and rock. Most are only a few miles in diameter and are found between the orbits of Mars and Jupiter, too small and far away to be seen easily in a small telescope. A few venture closer to the Sun and cross Earth’s orbit.
|

asteroidA rocky space object which can be from a few hundred feet to several hundred km wide. Most asteroids in our solar system orbit the Sun in a belt between Mars and Jupiter.

asteroidA minor planet, one of the many small celestial bodies revolving around the sun, most of the orbits being between those of Mars and Jupiter. Also called PLANETOID, MINOR PLANET. See under PLANET.

asteroidA rock in space. Can be found in asteroid belts, deadspace pockets, or Cosmic Anomalies. Most asteroids can be mined for ore, but some are purely decorative. For more info, see Asteroids and Ore.
